The economy over the past several years has been built on the backs of discretionary consumption. All the non-essential stuff consumers have been buying was approximately 40% of GDP. Obviously, that's a sizable amount in terms of dollar contributions and people employed. A couple trillion dollar stimulus package would probably be needed to alleviate some of the damage done. The pinball industry will definitely suffer some headwinds. Whether they drop prices a bit to restart the machine or stay "stubborn" and hold the line will be interesting to see.
Regarding investing, everything is a falling knife right now and although trying to time the market is futile, I would wait before entering if you have cash on the sidelines. Buying on a dip is one thing. Buying on a meteorite crater when larger meteorites are still landing is quite another thing. Just about every stock will be a screaming buy when we begin stringing together some positive sessions. If there are any "winners" right now it would be streaming companies and telecommute technologies.
